Technical Field

[0001] This utility model relates to the field of new energy battery box technology, specifically to a one-time pressing and riveting device for battery box mounting sleeve. Background Technology

[0002] Before installing new energy battery boxes on vehicles, mounting sleeves need to be pre-installed on the battery boxes to facilitate quick positioning and installation, ensuring assembly efficiency and accuracy.

[0003] The mounting sleeves are mainly fixed in the mounting holes on the edge of the battery box using a press-fit method. In the existing technology, press-fitting is mainly carried out by operators using handheld press-fitting equipment to individually press-fit the sleeves in each mounting hole. Because handheld press-fitting equipment is heavy and difficult to operate, it often results in low press-fitting assembly efficiency and poor product consistency. Utility Model Content

[0004] In view of this, the present invention provides a one-time riveting device for battery box mounting sleeves, which can rivet each mounting sleeve at one time, ensuring riveting efficiency while also ensuring product consistency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A one-time riveting device for battery box mounting sleeves includes a tooling platform with rollers distributed along its length for conveying battery boxes. The tooling platform has a one-time riveting station with a front positioning component at its front end. This front positioning component is convex upwards to position the battery box to be assembled. Lifting positioning pin components are provided on both sides of the one-time riveting station. When the front of the battery box abuts against the front positioning component, the lifting positioning pin components can be inserted upwards into positioning holes on both sides of the battery box. Above the one-time riveting station are riveting components. When the battery box is positioned and installed on the one-time riveting station, each riveting component corresponds one-to-one with each mounting sleeve on the circumferential edge of the battery box in the height direction. The riveting components can press the corresponding mounting sleeve downwards into the battery box.

[0007] With the above structure, after the battery box moves into the one-time riveting station, the front positioning component can limit the movement of the battery box to ensure that the battery box moves into place. Then, the lifting positioning pin component limits the battery box in one step, while avoiding shaking of the battery box during the riveting process. Finally, the riveting component is used to rivet each set in one go, which greatly speeds up the riveting efficiency. At the same time, the use of machine riveting ensures the consistency of the products.

[0008] Preferably, the one-time riveting station also has side support blocks located on both sides of the middle of the tooling platform. After the battery box is moved into the one-time riveting station, the bottom of the side beam of the battery box can abut against the top of the side support block. With the above structure, the bottom of the riveting stations on both sides of the battery box can be supported, preventing the battery box from being deformed by pressure.

[0009] Preferably, the riveting assembly includes a first cylinder disposed at the top of the tooling platform and a riveting block disposed at the lower end of the first cylinder, the riveting block having a downwardly extending guide rod. With this structure, the riveting block is driven downward by the first cylinder, enabling the mounting sleeve to be riveted into the mounting hole of the battery box.

[0010] Preferably, a gantry support is provided in the middle of the tooling platform, and the riveting components are evenly distributed around the top circumference of the gantry support. This structure ensures stable installation of the riveting components.

[0011] Preferably, the lifting positioning pin assembly includes second cylinders disposed on both sides of the middle portion of the tooling platform and positioning pins connected to the top of the second cylinders, the positioning pins being inserted into the side support blocks. With this structure, the positioning pins further limit the positioning of the battery box, while ensuring that the battery box does not wobble during riveting, thus guaranteeing the quality of the riveting.

[0012] Preferably, the front positioning assembly includes a third cylinder disposed at the front end of the middle section of the tooling platform and a limiting post connected to the top of the third cylinder. With this structure, the limiting post ensures the battery box is moved into position, thereby guaranteeing riveting efficiency.

[0013] Preferably, the front and rear ends of the one-time riveting station also have bottom support components, which include a fourth cylinder and a support column connected to the top of the fourth cylinder. This structure provides support for the bottom of the riveting positions at the front and rear ends of the battery box, preventing deformation of the battery box under pressure.

[0014] Preferably, the tooling platform also has an unloading station and a placement station, which are located on the front and rear sides of the one-time riveting station, with the front positioning component close to the unloading station. This structure enables rapid riveting of the battery box.

[0015] Preferably, two sets of the front positioning components are provided, symmetrically arranged on both sides of the front end of the one-time riveting station. This structure ensures that the battery box will not shift due to the continuous force of the rollers after it has been moved into place.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The battery box mounting sleeve one-time riveting device provided by this utility model can limit the movement of the battery box after it moves into the one-time riveting station. The front positioning component can limit the movement of the battery box to ensure that the battery box moves into place. Then, the lifting positioning pin component limits the battery box in one step, while avoiding shaking of the battery box during the riveting process. Finally, the riveting component is used to rivet each set in one go, which greatly speeds up the riveting efficiency. At the same time, the use of machine riveting ensures the consistency of the product.

[0018] 2. The bottom support components set at both ends of the one-time riveting station, and the side support blocks set on the left and right sides of the one-time riveting station, can support the bottom of the battery box at the riveting position and prevent the battery box from being deformed by pressure.

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0027] The one-time riveting device described in this embodiment is used for processing. Figure 7 The battery box 9 shown has side beams 9a installed on the left and right sides. Mounting holes 9b are formed on the side beams 9a and the front and rear ends of the battery box 9. Mounting sleeves 10 are installed in the mounting holes 9b. The mounting sleeves 10 have a central through hole 10a. The side beams 9a also have positioning holes 9c.

[0028] like Figure 1 and Figure 2 As shown, a one-time riveting device for mounting a battery box sleeve includes a tooling platform 1 for placing the battery box. Rollers 2 are distributed along the length of the tooling platform 1, and the rollers 2 can transport the battery box 9 on the tooling platform 1. The tooling platform 1 has a one-time riveting station b, and a front positioning component 4 is provided at the front end of the one-time riveting station b. The front positioning component 4 can be in an upward protruding state to perform front abutment positioning of the battery box 9 to be assembled. Lifting and lowering positioning elements are provided on both sides of the one-time riveting station. Positioning pin assembly 5: When the front end of the battery box 9 abuts against the front positioning assembly 4, the lifting positioning pin assembly 5 can be inserted upward into the positioning holes 9 on both sides of the battery box 9. Above the one-time riveting station b, there are also riveting assemblies 3. When the battery box 9 is positioned and installed on the one-time riveting station b, each riveting assembly 3 corresponds to each mounting sleeve 10 on the circumferential edge of the battery box 9 in the height direction. The riveting assembly 3 can press the corresponding mounting sleeve 10 downward into the mounting hole 9b on the battery box 9.

[0029] By using the one-time riveting station b, the riveting efficiency is greatly accelerated, while also ensuring product consistency.

[0030] In this embodiment, the roller 2 can be controlled by a motor to rotate, so that the battery box 9 can move automatically on the tooling platform 1. Alternatively, the battery box 9 can be manually pushed, and the rotation of the roller 2 can make the battery box 9 move on the tooling platform 1.

[0031] like Figure 2 and Figure 6 As shown, the one-time riveting station b also has side support blocks 6 set on both sides of the middle part of the tooling platform 1. When the battery box 9 moves into the one-time riveting station b, the bottom of the side beam 9a can abut against the top of the side support block 6, thereby avoiding the side beam 9a from being deformed by pressure during riveting.

[0032] Similarly, such as Figure 2 and Figure 4 As shown, there are also bottom support components 8 on the front and rear sides of the one-time riveting station b. The bottom support components 8 include a fourth cylinder 8a and a support column 8b connected to the top of the fourth cylinder 8a. The support part 8b can support the bottom of the riveting position corresponding to the front and rear ends of the battery box 9, thereby preventing the front and rear ends of the battery box 9 from being deformed by pressure during the riveting process.

[0033] like Figure 2 and Figure 5As shown, a gantry support 7 is fixedly installed in the middle of the tooling platform 1. The riveting assembly 3 includes a first cylinder 3a fixedly installed on the top of the gantry support 7 and a riveting block 3b disposed at the lower end of the first cylinder 3a. The riveting block 3b has a downwardly extending guide rod 3c. In this embodiment, a total of fourteen sets of riveting assemblies 3 are provided on the top of the gantry support 7. The fourteen sets of riveting assemblies 3 are evenly distributed around the top circumference of the gantry support 7. Among them, five sets of riveting assemblies 3 are evenly distributed on each of the left and right sides of the gantry support 7, and two sets of riveting assemblies 3 are evenly distributed at each of the front and rear ends of the gantry support 7. Two sets of bottom support assemblies 8 are respectively provided on the front and rear sides of the one-time riveting station b. With this design, by driving the first cylinder 3a, the riveting block 3b can be driven downward to rivet each mounting sleeve 10. The guide rod 3c can pass through the central through hole 10a to ensure that the mounting sleeve 10 can be stably riveted.

[0034] like Figure 5 As shown, the lifting positioning pin assembly 5 includes a second cylinder 5a fixedly installed on both sides of the middle part of the tooling platform 1 and a positioning pin 5b connected to the top of the second cylinder 5a. The positioning pin 5b passes through the side support block 6. When the battery box 9 moves into place, the second cylinder 5a can drive the positioning pin 5b to move upward and pass through the positioning hole 9c, so as to ensure that the battery box 9 will not shake, thereby ensuring that the riveting assembly 3 is more stable when riveting downward.

[0035] like Figure 4 As shown, the front positioning component 4 includes a third cylinder 4a installed at the front end of the middle part of the tooling platform and a limiting post 4b connected to the top of the third cylinder 4a. The third driving cylinder 4a can drive the limiting post 4b to rise upward and protrude from the roller 2, thereby limiting the movement position of the battery box 9.

[0036] In this embodiment, two sets of front positioning components 4 are provided. The two sets of front positioning components 4 are symmetrically arranged on both sides of the front end of the one-time riveting station b. With this design, when the battery box 9 is moved into place, the battery box 9 will not shift due to the continuous force applied by the roller 2, which helps to quickly perform riveting.

[0037] In this embodiment, the second cylinder 5a, the third cylinder 4a, and the fourth cylinder 8a are all fixedly installed at the bottom of the tooling platform 1, and are all in a retracted state when not in use. Specifically, the top of the positioning pin 5b is lower than or flush with the top of the side support block 6, and the top of the limiting post 4b and the top of the support post 8b are lower than the top of the roller 2. In addition, the first cylinder 3a is also in a retracted state when not in use. This design facilitates the smooth movement of the battery box 9 on the tooling platform 1.

[0038] like Figure 1As shown, an operation panel 11 is also fixedly mounted on the tooling platform 1. The operation panel 11 is electrically connected to the controllers of each cylinder and roller 2. This design makes operation more convenient and further improves the riveting efficiency.

[0039] like Figure 1 As shown, the tooling platform 1 also has an unloading station c and a placement station a. The unloading station c and the placement station a are respectively set on the front and rear sides of the one-time riveting station b. The placement station a is used to place the battery box 9 to be riveted, while the unloading station c is used to place the riveted battery box 9.

[0040] Based on the above structure, the specific usage process of the one-time riveting device for mounting the battery box sleeve is as follows:

[0041] The operator first places the battery box 9 to be riveted in placement station a and places the mounting sleeve 10 in the mounting hole 9b. Then, the operator controls the third cylinder 4a to extend through the control panel 11, causing the limiting post 4b to protrude upwards from the roller 2. The operator then drives the roller 2 to rotate through the control panel 11, moving the battery box 9 from placement station a to the one-time riveting station b. When the front end of the battery box 9 touches the limiting post 4b, the bottom of the side beam 9a is supported on the top of the side support block 6. The operator then controls the roller 2 to rotate through the control panel. 11 controls the positioning pin 5b to pass upward into the positioning hole 9c, and controls the limiting post 4b to rise upward and support the bottom of the corresponding riveting positions at the front and rear ends of the battery box 9. Then, through the operation panel 11, each riveting component 3 is controlled to press downward synchronously, so that each mounting sleeve 10 is pressed into each mounting hole 9b synchronously. Finally, through the operation panel 11, each cylinder is controlled to retract and the roller 2 is controlled to rotate, so that the battery box 9 moves from the one-time riveting station b to the unloading station c, thus completing the riveting of the entire battery box 9.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
